Why tertiary carbonium ions are more stable than the primary and secondary carbonium ions?

because they are. Knowwhatamsaying
I would say its mainly due to the fact that that tertiary have more alkyle group (CH3) thus its more stable. Primary has one secondary has two and tertiary 3 (see a patern there)

Why tertiary carbocation is more stable?
due to hypercongugation
Does rearrangement of carbocation take place in Lucas test?
Yes, the organization of carbocation does take place in a Lucas test. Tertiary carbocations are the most stable; while primary carbocations are the most reactive.
Why is tertiary amine more stable than ethanol?
Tertiary amines have alkyl groups around the central atom (nitrogen) while ethanol has hydrogen atoms and one hydroxyl group around the carbon atoms. As a result, ethanol is more prone to attack by other groups while in tertiary amines, stearic hindrance doesn't allow attack of incoming groups. So, tertiary amines are more stable than ethanol.
Will IPA react with HCL?
Not likely as ipa is a secondary alcohol and will not form as stable a carbocation as tertiary alcohols such as tert-butyl alcohol in this SN1 first order nucleophilic substitution reaction. However, ZnCl2 would facilitate the formation of the carbocation with ipa and the nucleophile (Cl-) could then attack with the subsequent formation of the alkyl halide.
Why primary and secondary standard solutions are needed in analysis.?
Primary standards have some peculiar propertiesThey are nonsensitive to atmospheric oxygenThey have known formula and molecular weightThey are usually high molecular weight compoundsThey have a constant concentration /uniform composition for a long period of timeThey are powerful reactantsSecondary standards areInfluenced by atmosphere/environmentConcentration change over timeUsually powerful reactantsUsually cheap & easy to useZeryawkal Ergetie(Msc in pharmaceutical Analysis )
What would form a stable community faster primary or secondary succession?
Secondary succession will form a stable community faster. During primary succession the pace of succession remains slower.
How many trophic levels are in the food chain?
There are four trophic levels in an ecological pyramid. They are primary producers, primary consumers, secondary consumers, and tertiary consumers.
Why tertiary alcohol is more reactive?
Tertiary alcohols are also bonded to three other carbon atoms (whereas secondary alcohols are bonded to two, primary alcohols to one). These other carbon atoms share their electronegative charges with the middle carbon.
What is the development of a stable community from new land?
Development of stable community in new land is called secondary succession .It is slower as compared to primary succession .
What type of alcohols is fischer esterification limited to?
Primary and secondary alcohols are commonly used in the process and work efficiently with an acid catalyst but tertiary alcohols can also be used in some cases under the right conditions. One the reasons that it is more difficult to use tertiary alcohols is because of the steric hinderance which exists in the molecule so there is too much molecular interaction for a stable compound to form.
Why tertiary carbocation is more stable?
due to hypercongugation
Does rearrangement of carbocation take place in Lucas test?
Yes, the organization of carbocation does take place in a Lucas test. Tertiary carbocations are the most stable; while primary carbocations are the most reactive.
What is a secondary reference electrode?
The primary reference electrode is the hydrogen electrode, which is rather fiddly to work with. Secondary references are chosen for their stability and their reliable potentials so others can be calibrated against them.
How do you set up a transformer efficiency test?
You'll need a clean, stable primary side voltage source. You'll measure and monitor it throughout the test. You will need to measure primary current, too. You'll need a stable secondary resistance of known value, and you'll have to monitor voltage across it throughout the test. If you want to measure current, you can use an "unknown" resistance - as long as it is stable. You have a choice, and you can make your calculations based on either one. Your equipment will have to be "accurate" at least to the degree of accuracy you wish in your results. Hook up your resistance to the secondary, hook your equipment up to the various places you'll need it to make your measurements, plug in the primary and flip the switch. Observe and record. Your data will allow you to make calculations. Primary voltage times primary current equals primary power (power into the primary). Secondary voltage times secondary current will equal secondary power (power out of the secondary). There wil be a bit more power "put into" the primary than is "taken out of" the secondary because of losses within the transformer. (These will be resistive losses in the wire as well as inductive losses in the core - eddy currents.) And that is what efficiency speaks to. Transformer efficiency can be calculated using the following formula: Efficiencytransformer in % = 100 x (Powersecondary / Powerprimary) If you opt to use secondary voltage and the resistance of the resistive load to make your calculations for the secondary side power, it will be found by using this formula: Powersecondary = (Voltagesecondary)2 / Resistanceload Either path should lead to the same destination. And just so you know, if you use secondary current and the resistance of the load to make the calculation, that is done using this formula: Powersecondary = (Currentsecondary)2 x Resistanceload All roads lead to Rome.
Can a flyback transformer be powered by nothing but a car battery and wires?
A transformer is an AC device in that it requires a changing current to be input in order to see an output. Attaching a 12V battery to the primary side of the transformer will generate a voltage on the secondary for a short amount of time. Once the primary current has risen to a stable level, there will be no output voltage on the secondary. There will also be voltages on the secondary and the primary when the battery is disconnected from the transformer. A flyback transformer relies on an AC current at the primary to generate a high voltage at the secondary output. Circuitry to make changes to the primary current will be needed in addition to the battery. Warning: removing the battery from the primary winding of the transformer is liable to generate a very high voltage across the primary coil as well as the secondary. In some cases, they can be lethal. Do not experiment with transformers unless you are properly qualified and supervised.
Why Markonikov's rule is not applicable for alkynes?
Due to two reasons, 1- except terminal alkynes no hydrogen atom is attached to triple bonded carbons and 2- carbonium ion having a double bond is not stable.
Why is tertiary amine more stable than ethanol?
Tertiary amines have alkyl groups around the central atom (nitrogen) while ethanol has hydrogen atoms and one hydroxyl group around the carbon atoms. As a result, ethanol is more prone to attack by other groups while in tertiary amines, stearic hindrance doesn't allow attack of incoming groups. So, tertiary amines are more stable than ethanol.
